Visibility, Selectivity, Optimization, and Interaction of Natural Tannin Dye from Ceriops tagal (Perr.) C.B. Rob. Extract for Plant Tissue Staining Rasuane Noor, Maryani Maryani, Bambang Retnoaji, Edia Rahayuningsih Journal of Multidisciplinary Applied Natural Science, 2025 Tissue staining improves cellular visualization for microscopic analysis. This study explores tannin dye from Ceriops tagal as a sustainable, eco-friendly alternative for plant histology. Its strong affinity to cotton cellulose suggests effective staining potential. The research assesses tissue visibility, mordant specificity, color contrast, and dye–tissue binding interactions. Tissue staining enhances the visualization of cellular structures, facilitating microscopic analysis. Developing safe, cost-effective, and environmentally friendly natural dyes is essential for sustainable histological applications. Tannin dye extracted from C. tagal binds effectively to cotton cellulose, indicating its potential for plant tissue staining. This study evaluates the visibility of stained plant tissues, mordant selectivity, color contrast optimisation, and chemical bonding interactions. The stem sections of sunflower (Helianthus annuus L.) were stained with C. tagal tannin dye. Mordants used included ferrous sulfate (FeSO₄), aluminum sulfate (Al₂(SO₄)₃), and calcium carbonate (CaCO₃), with synthetic safranin serving as a control. Color contrast optimization was performed using response surface methodology (RSM), analyzing dye concentration, immersion duration, and mordant concentration. Color contrast (ΔE) was measured using colorimetry via a smartphone application, while chemical interactions were examined through Fourier transform infrared (FTIR) spectroscopy. The results showed that tannin dye adhered well to plant tissues, producing colors ranging from sepia brown to baker’s chocolate. Al₂(SO₄)₃ produced the highest contrast (ΔE = 79.7). Optimal staining conditions were achieved with 44.233 g/L tannin dye, 73.636 s of immersion, and 110.454 g/L Al₂(SO₄)₃ as the mordant. FTIR analysis revealed bonding interactions, evidenced by peak intensity shifts at 2922 and 1100 cm⁻¹. C. tagal tannin dye demonstrates strong potential as a natural, sustainable plant tissue stain with effective mordant selectivity and contrast. Further research is recommended to expand its application across diverse plant species and to standardize protocols for broader histological use.
The knowledge mapping of HIV/AIDS in Indonesians living on six major islands using the Indonesian version of the HIV-KQ-18 instrument Bustanul Arifin, M. Rifqi Rokhman, Zulkarnain Zulkarnain, Dyah Aryani Perwitasari, Marianti Mangau, Saidah Rauf, Rasuane Noor, Retna Siwi Padmawati, Muhammad Nasrum Massi, Jurjen van der Schans, Maarten J. Postma Plos One, 2023 Indonesia’s total number of HIV/AIDS cases is still high. Inadequate knowledge about the risk of HIV infection will influence HIV prevention and therapy. This study aimed to map the level of HIV-related knowledge among Indonesians living on six major islands in Indonesia and investigate the relationship between socio-demographic characteristics and HIV/AIDS knowledge. This cross-sectional study used the Bahasa Indonesia version of the HIV Knowledge Questionnaire-18 items (HIV-KQ-18) Instrument. Data collection was done online through the Google form application. A total of 5,364 participants were recruited. The participants from Java had the highest degree of HIV/AIDS knowledge, which was 12.5% higher than participants from Sumatra, Kalimantan, Sulawesi, Papua, and Maluku. Linear regression showed that region, educational level, monthly expenditure, occupation, background in health sciences, and workshop attendance were significantly correlated with HIV knowledge. Participants typically understand that "HIV/AIDS transmission" only happens when sex partners are changed. Additionally, the government still needs improvement in HIV/AIDS education, particularly in the HIV incubation period, HIV transmission from pregnant women to the fetus, and condom use as one method of protection. There are disparities in HIV/AIDS knowledge levels among the major islands of Indonesia. Based on these findings, the government’s health promotion program to increase public awareness of HIV/AIDS must be implemented vigorously. Additionally, in line with our research findings, it is essential to broaden the scope of HIV/AIDS education and promotion materials.
Adaptation and validation of the HIV Knowledge Questionnaire-18 for the general population of Indonesia Bustanul Arifin, M. Rifqi Rokhman, Zulkarnain Zulkarnain, Dyah Aryani Perwitasari, Marianti Manggau, Saidah Rauf, Rasuane Noor, Retna Siwi Padmawati, Maarten J. Postma, Muhammad Nasrum Massi, Jurjen van der Schans Health and Quality of Life Outcomes, 2022 Background Despite a global decline in new HIV/AIDS cases in low-middle countries, cases are increasing in Indonesia. Low knowledge about the disease among the general population is one of the major factors responsible for this trend. Indonesia does not have a validated instrument to assess HIV/AIDS knowledge. The HIV Knowledge Questionnaire-18 (HIV-KQ-18) has been translated into several languages and is one of the most extensively used instruments for assessing HIV/AIDS knowledge. This paper describes the process of adapting and validating the HIV-KQ-18, an instrument to assess the level of HIV/AIDS knowledge in the general population of Indonesia. Methods In the adaptation phase, feedback for the initial Bahasa Indonesia version was gathered from two HIV activists, an obstetrician, two general practitioners, and 60 pilot participants. At the validation stage, we distributed the instrument link via Google Form to 6 major regions in Indonesia. Validity was measured using known-group validity and construct validity. The construct validity was assessed using an exploratory factor analysis (EFA) with a polychoric correlation matrix. Cronbach’s alpha was used to analyze the internal consistency. Results Based on the findings in the adaptation phase, additional descriptions (namely synonyms or examples) were added to 6 items to make them more understandable. In the validation phase, 1,249 participants were recruited. The a priori hypothesis in known-group validity was supported. We also found three items that did not meet the construct validity. Based on the acceleration factor approach to interpret the scree tree in the factor analysis, using only two factors was preferable. Cronbach's alpha values were 0.75 and 0.71 representing good internal reliability. Conclusion The HIV-KQ-18 Bahasa Indonesia is considered a valid and reliable instrument to assess the level of HIV/AIDS knowledge in Indonesia.
Variation pumakkal formula against NPK levels of Household liquid waste organic fertilizer Rizki Kurniawan, Anak Agung Oka, Agus Sutanto, Hening Widowati, Rasuane Noor Iop Conference Series Earth and Environmental Science, 2022 More than industrial trash, household liquid waste is a societal concern caused by human activities. Using Pumakkal starters, this research turns domestic liquid waste into organic fertilizer. This research was conducted in several stages. The first was to make household waste liquid fertilizer with pumakkal formula P1 (3 bacterial isolates), P2 (6 bacterial isolates), P3 (9 bacterial isolates), P4 (12 bacterial isolates), P5 (15 bacterial isolates). The second was the test quality of household waste liquid fertilizers. The results showed the levels of NPK have quality standards of 2-6% with grades N (0,337), P (1,755), and K (3,818) at the highest treatment, and the values of N, P, K meet SNI. The C-Organic levels have a quality standard (minimum 10) with the value of 15,706 in the P5 treatment, and thus C-Organic exceeds SNI. The ratio level of C/N has a quality standard (≤25) with a value of 93,191 at the smallest P5 treatment compared to other treatments resulting in the ratio of C/N exceeding SNI. The pH has a quality standard (4-9) with a value of 6,176 on the P5 treatment, so the pH has met the SNI.

Coffee pulp fermentation techniques for the sustainable organic agriculture A Sutanto, A Achyani, R Noor, D Subandowo, F Thresia Journal of Physics Conference Series, 2020 Abstract This paper discusses the potential issues in Lampung province of Sumatera, Indonesia where the majority of the people are to earn a livelihood as a coffee farmer. This place has potential benefits to increase land of coffee farms in order to make greater capacity and economic sector by using an environmentally-friendly technology. To date, the utilization of coffee pulps is only by freely spreading to the coffee farms. In doing so, the technological fermentation by using Indigenous bacteria that has role to produce organic fertilizer of coffee pulps helps gain the soil fertility. This study used descriptive data analysis with community practical approach. The results show that the growth of coffee and other intercropping plants like chili is more fertilized, easy to flower, and it lengthens the shoot growth. In addition, the coffee production seems like changing in the amount of quantity that tends to get better. The significant number also showed by the production of chili because the harvest season is longer than usual. Another advantage by using this fermentation is that the use of non-organic fertilizer can be reduced up to level 80 per cent. Likewise, this condition automatically dropped the production cost.
